Flammable liquid. It is hygroscopic and does not corrode metal. It reacts with dibasic acid to generate polyester, reacts with nitric acid to generate nitrate, and reacts with hydrochloric acid to generate chlorohydrins. With dilute sulfuric acid at 170 ºC heating into propionaldehyde.
Oxidation with nitric acid or chromic acid generates glycolic acid, oxalic acid, acetic acid, etc. Reacts with aldehydes to form
acetals. Dehydration of 1,2-Propanediol to Propylene Oxide or Polyethylene Glycol
It is often used as an excipient in many pharmaceutical formulations to increase the solubility and stability of the chemical Product.
